It’s Monday morning - give it time. When I was SIRPed last year, the meeting notice came on a Tuesday for the next day with my LL4. Told that Wed that Friday was my last day, then after the meeting I got the SIRP paperwork.
Plus you need to realize not all areas will be hit simultaneously, so this could drag out a couple of weeks or more. It all really depends on the number. However, since it was leaked the the news, especially the Free Press, you can count on something happening.
Let me ask OP something; even if you area and/or you are not hit this time, how much longer do you want to put yourself through the mess? Sure, the job market is tough, but you still should be looking anyway. There is not a prize for being the last one off the Titanic.
